Talking Points

Recent interactions between the hosts and their guests.

Carbon removal that utilities actually want
Q: What are the benefits for the facilities beyond CO2 removal, and how do regulators view this?
By boosting microbial efficiency, the treatment plant can remove pollutants more effectively, reducing both OPEX and CAPEX. Regulators are a major consideration; the strategy relies on working within existing permits and focusing on education to align incentives and ease deployment.
Carbon removal that utilities actually want
Q: Can you tell us about CREW and the work you've been doing since the company was founded in 2022?
The core idea was to commercialize alkalinity-based carbon removal by integrating it into wastewater systems because they check all the market boxes: existing pre-permitted infrastructure, high measurability, and permanent, verifiable carbon removals, while also improving plant efficiency.
Carbon removal is not one thing
Q: What practical steps should early-stage carbon removal startups take to get ready for commercial deals and project finance?
Startups should augment their teams with experienced legal and licensing advisors, build both technical and commercial readiness, plan for extended negotiation timelines with corporates, and design adaptable business models that can deliver revenue today while pursuing longer-term, larger-scale projects.
Carbon removal is not one thing
Q: How have financing models evolved for carbon removal as the market matures?
Financing has shifted from generic exploration to more structured, pathway-specific approaches, including project finance and early loss-bearing structures, with involvement from foundations and corporate off-take commitments; the focus is on delivering repeatable cash flows and de-risking early-stage technology.
Carbon removal is not one thing
Q: Can you explain your investment thesis and the makeup of CounterAct's portfolio in carbon removal?
CounterAct emphasizes specialization in carbon removal, evaluating pathways by their unique economics and integration opportunities rather than chasing a single technology; the portfolio includes diverse pathways with a strategy to back those showing practical, near-term revenue potential and opportunities for industrial integration.
